And to change things up even more, many of the battles have special conditions that force you to change your strategies: You might have to get all the enemies down to 1 HP before any of them will die, or your monsters' max HP might decline with each turn, and so on.

Basically, while the gameplay here will be very familiar to an RPG veteran, virtually every aspect of it is twisted in some way. This keeps you on your toes. Also, the ability to regenerate after every battle and the ability to save anywhere ensures that these constant changes to the rules are exciting and challenging rather than cheap and frustrating.

The graphics and sound are a nice touch as well. When Zeboyd Games took over the series for Episode 3, it went with a classic 16-bit graphical and musical style, and this returns for Episode 4. The music in particular can be cheesy at times, but it definitely reminds you of older video games.

It’s amazing to me that all of this costs a mere $5--this is not the longest game ever, by any stretch, but the sheer quality of the campaign makes it a steal at this price point. On the Rain-Slicked Precipice of Darkness 4 manages to be a trip down memory lane, a hilarious collection of Penny Arcade humor, and a worthy RPG all at once.
